A transmit/receive (T/R) module adapted for use in a radar system. The module has a unified structure including a layered substrate on and in which two T/R channel circuits are integrated. The channel circuits make use of power distribution, channel controller, and RF signal routing circuitry, partly on a channel shared basis. In the RF routing circuitry, respective coupler elements are employed to combine RF receive signals for output to an RF receive manifold and to split an RF transmit signal from a transmit manifold into separate RF transmit signals for input to the T/R channel circuits.
L'invention concerne un module émetteur/récepteur (E/R) destiné à un système radar. Le module a une structure unifiée constituée d'un substrat en couches sur et dans lequel sont disposés deux circuits de canaux E/R. Les circuits de canaux sont associés à un module d'alimentation, à un contrôleur de canal et à un circuit d'acheminement des signaux HF, en partie sur une base de partage des canaux. Dans le circuit d'acheminement HF, des éléments coupleurs combinent les signaux de réception HF, de façon à les transmettre à un collecteur de réception HF, et divisent un signal d'émission HF provenant d'un collecteur d'émission en signaux d'émission HF distincts, de façon à les transmettre aux circuits de canaux E/R.
